Design of an Atmospheric Model Based on a Generalized Vertical Coordinate

摘要: Abstract Although there are important advantages in the use of an isentropic vertical coordinate atmospheric models, it requires overcoming computational difficulties associated with intersections surfaces earth’s surface. In this paper, authors present a model based on generalized coordinate, ζ = F(θ, p, pS), which can be combined terrain-following σ near surface smooth transition between two. One key issues developing such is to satisfy consistency predictions pressure and potential temperature. presented maintained by equation that determines mass flux. A procedure properly choose pS) also presented, guarantees monotonic function height even when unstable stratification occurs. discretization, Charney–Phillips grid used since, wit...
